Buy a recharge kit from an auto parts store. This will include a charging valve/hose, and cans of freon. It's best to get a charge hose with a pressure gauge on it. Screw can onto tap end of the charging hose, turn piercing valve clockwise until it stops. Attach quick connector to the low side outlet of the AC system (this fitting is foolproof. It will only fit on the correct connector). Turn vehicle on, turn AC on MAX with fan on high. Go back to the charging hose and turn the piercing valve counter clockwise to let the freon out of the can and into the hose, into the AC system. Make sure AC clutch is cycling to ensure movement of freon into the AC system. Do not overcharge the system, or you may burst parts. Most systems only hold 2 cans worth. To achieve best results, you must evacuate the entire AC system of all freon & pressure before charging.
